Title: Multi-layer wall covering material for space heating
IPC: F24D13/02
Filed: 1964-05-26
Abstract: 1,115,643. Mounting electric resistance heating films. P. EISLER. 26 May, 1965 [26 May, 1964], No. 22376/65. Divided out of 1,115,642. Heading H5H. [Also in Division B5] Materials and adhesives utilized in a rollable laminated wall covering material, incorporating an electric resistance heating film 71 between at least two other rollable layers 85, 86 and having a protective surface layer or coating on one side, are such as to enable one or more layers, e.g. a decorative surface layer 73, 74, 75 of wallpaper, or the heating film 71 and layers above it, to be delaminated without damaging the underlying layers. The film 71 may be a metal foil with a pattern of slits or a conductive coating of carbon or graphite. The foil may be crimped, and additional insulating and metal foil layers may be provided so that the film is itself a multi-layer construction. The protective coating may be a polyvinylacetate based copolymer. The layer(s) to be delaminated may be pervious to water and secured by a water-soluble adhesive, the remaining layers being impervious to water and/or secured by an adhesive which is resistant to water. Alternatively the layer(s) to be delaminated may be secured by an adhesive which softens at a temperature considerably higher than that developed by the heating film, the remaining layers being secured by an adhesive which is either resistant to temperature or is protected by a thermal insulating or reflecting layer, thus enabling delamination to be effected with the aid of a heated roller. The material, Fig. 1, secured to a wall 76 comprises a thermal insulating layer 77; a heating film 78 comprising a patterned foil 79 between paper insulators 81 and 82; a thermal insulating layer 83 of easily dentable material such as foamed or expanded synthetic resin material or corrugated paper; a layer 80 which is substantially more resistant to denting, e.g. a metal foil which also acts as a thermally reflecting layer; a second heating film 84 comprising a patterned foil 71 between insulating papers 85 and 86; and a layer of wallpaper 73, 74, 75. In an alternative form, Fig. 6, the multilayer material 180 including one or two heating films has a thermal insulating layer 93 with adjustably inflatable cavities 94. This material may form a decorative scroll, blind or curtain, a portable screen or temporary wall surface, or the main component of the wall of an inflatable tent. The heating films may be connected in groups to series/parallel switching circuits which may be controlled by thermostats.

Title: Improvements in or relating to the manufacture of electric discharge devices
Inventor: BRODIE IVOR
IPC: H01J9/04
Filed: 1955-08-09
Abstract: 797,842. Cathode materials and processing. GENERAL ELECTRIC CO., Ltd. Aug. 2, 1956 [Aug. 9, 1955], No. 22985/55. Class 39(1). In the manufacture of an electric discharge device other than a thermionic valve, the emissive portion of the thermionic cathode is made by mixing together powdered alkaline earth metal carbonates, powdered nickel and/or cobalt, and at least one powdered alloy of nickel and/or cobalt and at least one reducing agent (silicon, magnesium, aluminium, titanium, zirconium or tungsten), pressing the mixture into a compact body and heating the body so as to sinter the powder and decompose the carbonates to produce the corresponding oxides. The carbonates constitute between 10 and 50 per cent by weight of the mixture and include at least 10 per cent by molecular proportion of barium carbonate and the reducing agents are present in such a proportion that there are not less than 2À5 atoms of barium to each atom of the reducing agent. The preferred proportions are about 70 per cent by weight of powdered nickel and/or cobalt, 30 per cent by weight of powdered alkaline earth metal carbonates and about 35 per cent by weight of a powdered nickelsilicon alloy comprising about 30 per cent by weight of silicon. Preferably the compact body is formed by pressing the mixture at a pressure of 80 tons/sq. in. into one end of a metal tube which forms part of the cathode so that a disc of the mixture is formed which is cold welded at its rim to the end of the metal tube. The reduction takes place at a temperature of 1050‹C.
Patent GB-229937-A (GB)
Abstract: 229,937. White, A. E., (International Business Machines Corporation, [formerly Computing-Tabulating-Recording Co.]). Aug. 8, 1924. Addition to 223,067. Factory and like time-records, cardtype; time and cost, computing. - The recorder described in the parent Specification is fitted with means for preventing advance of the time wheel after it has been reset to zero, until a zero record has been taken. The time type-wheels 10 together with the ratchet-wheel 13 and aligning- wheel 12 are fixed to a shaft 21 and reset to zero by manually turning the shaft clockwise, and at the zero position a stop-pin 23 on the aligning wheel is engaged and held fast by a pivoted dog 24. On operating the handle 22 to print by means of the hammer 28<1>, a link 28 pivoted to the trip-member 38 rocks a bail 27 anticlockwise thus raising the tail 26 of the dog 24 and releasing the stop pin 23. This movement also rocks the aligning pawl 32 to align the type wheel for printing. When the pin 23 is engaged by the dog 24 the pawl 18 on the escapement-wheel 14 is arranged to be midway between two teeth on the ratchet-wheel 13 so that on the return movement of the handle the type-wheel moves through half a step under the action of a spring which has been wound during resetting and the parts come into the positions shown by full lines in Fig. 3. The type-wheel is now free to be advanced by the spring when the escapement 16 is operated by a magnet 17 energized from a master clock and as the pin 23 passes around, it allows the dog 24 to return under the action of a spring to the position shown in Fig. 1. Also spring-pressed against the pin 23 in the zero position is a cam surface 34 on a card-abutment lever 33 so that as the tyre-wheel advances, this lever is rocked and the card-abutment raised. An arm 35 on the lever 33 released a spring-controlled lever 36 to come in the path of a pin 37 on the trip-member 38 after the next actuation of the handle and prevent any further record being taken until the type-wheel has been zeroized, as in the parent Specification. The operating handle 22 may be removable and may have a part adapted to co-operate with the shaft 21 so that the handle acts as a resetting wrench. An identifying number may be printed on the record card from fixed type arranged near the time typewheel, and to facilitate changing of the time and value types they are arranged on brass bands removably fitted to the wheel.

Abstract: 723,223. Refuse vehicles; raising and tipping bins. EAGLE ENGINEERING CO., Ltd. Jan. 5, 1953 [Oct. 5, 1951), No. 23187/51. Classes 78 (3) and 78 (4). A pair of arms 12, Fig. 1, each mounted for limited pivotal movement on an arm 9 turned by power about an axis 5 on a refuse vehicle, serve to engage and lift a bin 18 until a bracket 23 on it engages a member 24 on the vehicle to tip the bin and discharge its contents into the vehicle. As the bin, which carries trunnions 16 engaged by means on the arms 12, is raised a pawl 12a on each arm 12 engages a stop 13 on the corresponding arm 9 so that the arms 9 and 12 move together; when however the bracket 23 engages the member 24 the resultant tipping motion of the bin causes the arms 12 to pivot relatively to the arms 9 to provide a rapid tipping motion. When a bin is to be lifted links 19 are swung about their pivots on the ends of the arms 12 into the position shown in broken lines in Fig. 2, in which slots 21 in the links engage the trunnions 16. As the arms 9 are subsequently raised by rams 6, Fig. 1, slots 14 in the arms 12 engage the trunnions 16 which are held captive by the links 19, withdrawal of which is prevented by pins 17 on the bin which engage the surfaces of curved heads 20 on the links. Slots 15 in the arms 12 prevent interference between the pins 17 and the arms 12 during the tipping motion. Each arm 12 comprises a pair of spaced plates between which the corresponding link 19 is pivoted. The arms 12 may be folded beneath the rear of the vehicle as shown in full lines in Fig. 2, the arms 19 being then supported by pins 25 which engage within the slots 14.
